Hereinafter, embodiments of the present invention will be described in detail with appropriate reference to the drawings.
In the description of each embodiment, the same constituent elements are denoted by the same reference numerals, and redundant descriptions are omitted.

<First Embodiment>
First, the plant cultivation container-plant complex according to the first embodiment will be described with reference to FIGS. 1 to 3. In the drawings to be referred to, FIG. 1 is a perspective view in which a part of a plant cultivation container-plant complex according to the first embodiment is broken. FIG. 2 is a process chart showing step by step a method for producing the plant cultivation container shown in FIG. FIG. 3 is a diagram for explaining a planting method according to the first embodiment.

[Constitution of plant cultivation container-plant complex]
As shown in FIG. 1, the plant cultivation container-plant complex 1 includes a plant cultivation container 10, a soil 20, and a plant 30 planted in the soil 20. Hereinafter, the soil 20, the plant 30, and the container 10 for plant cultivation will be described in this order.

(Soil)
The soil 20 is soil for cultivating the plant 30, and promotes planting and growth of the plant 30. The soil 20 is put in the planting portion 10a (see FIG. 2D) of the plant cultivation container 10 and is filled between the plant cultivation container 10 and the plant 30. The type of the soil 20 is not particularly limited in the present invention, and may be appropriately changed according to the type of the plant 30, the cultivation time of the plant 30, and the like. Further, slaked lime, bituminous lime, Kanuma soil and the like may be added as necessary.

(plant)
The plant 30 is planted in such a manner that the root 30a is stretched on the soil 20 introduced into the planting part 10a described later. The kind of the plant 30 is not particularly limited in the present invention, and may be a plant such as an azalea, a flower such as a sunflower, a grass such as a lawn, or the like. Moreover, there is no limitation in particular also about the growth degree of the plant 30, For example, a seedling may be sufficient.

(Container for plant cultivation)
The plant cultivation container 10 has a substantially rectangular parallelepiped shape in the first embodiment. In the center of the plant cultivation container 10, there is formed a planting portion 10 a that is a cylindrical space having an upper opening and into which the plant 30 is planted. That is, the plant cultivation container 10 is composed of a bottom portion 11 that serves as a bottom and a side wall portion 12.
However, the outer shape of the plant cultivation container 10 is not limited to a substantially rectangular parallelepiped shape, and may be, for example, a funnel shape, a hemispherical shape, or a bottomed cylindrical shape. Also, the size of the plant cultivation container 10 can be changed as appropriate according to, for example, the size and type of the plant 30 to be planted, the characteristics of the root growth method, etc. For example, the plant cultivation container 10 is molded into a small size. It can also be used for home gardening.

The bottom part 11 and the side wall part 12 of the container 10 for plant cultivation are formed by bonding wood chips, wood fibers, sand, and nutrients with a moisture curable adhesive.
Therefore, the plant cultivation container 10 is very light and easy to carry compared to an unglazed container generally called a flower pot. In addition, plastic square containers called planters and polyethylene containers called pots do not rot over time and need to be collected after use and must be disposed of as non-combustible waste. The plant cultivation container 10 is mainly formed of wood chips and wood fibers, and decays and disintegrates with time. Therefore, when the plant 30 is transplanted from the plant cultivation container 10 to other soil, etc. It is also possible to transplant the container 10 as it is to the other soil. Moreover, when the plant cultivation container 10 and the plant 30 are separated, the separated plant cultivation container 10 can be easily disposed as combustible waste.

  Moreover, since the container 10 for plant cultivation is mainly formed from a wood chip and wood fiber, it has a shock absorption property. Therefore, by installing the plant cultivation container 10 at, for example, a corner of a parking lot, damage to a vehicle or the like can be prevented. Furthermore, since the surface of the plant cultivation container 10 is mainly formed from wood chips and wood fibers, the appearance of the plant cultivation container 10 is not lost.

The bottom part 11 and the side wall part 12 have a gap at a predetermined porosity, and as shown by an arrow A1 in FIG. 1, oxygen-containing air, moisture, and the like can freely pass through the bottom part 11 and the side wall part 12. Yes. As described above, air or the like can freely pass through the bottom part 11 and the side wall part 12, that is, the air permeability is good, so that oxygen in the air is easily supplied to the root 30 a of the plant 30, and the growth of the plant 30 is preferably performed. Promotion is possible. Even if water is excessively supplied to the plant 30, excess water passes through the bottom portion 11 and the side wall portion 12 and is discharged to the outside of the plant cultivation container 10, so that the root 30 a of the plant 30 is not easily spoiled. ing.
Moreover, since the bottom part 11 and the side wall part 12 can be freely ventilated in this way, air or the like is easily supplied to the soil 20, so that the soil 20 is hardly cured. That is, since a general unglazed flower pot does not have air permeability, the soil in the flower pot tends to be hard, but according to the plant cultivation container 10, the soil 20 is hard to harden and the plant 30 grows suitably. , Easy to grow.

  In the first embodiment, the porosity is in the range of 5 to 40%. This is because if the porosity is lower than 5%, the air permeability tends to decrease and the growth of the plant 30 tends not to be promoted. On the other hand, if the porosity is higher than 40%, the soil 20 flows out.

Wood chips are obtained by processing wood into small pieces, and wood fibers are processed into fibers. And the wood chip and wood fiber have water retention.
Further, when water is sprayed on the plant 30, the wood chip and the wood fiber can retain excess water that has not been absorbed by the plant 30 and the soil 20 as indicated by an arrow A2 in FIG. On the other hand, when the soil 20 is dried, the water retained by the wood chip and the wood fiber can be supplied to the root 30a of the plant 30 through the soil 20 as indicated by an arrow A3.
Therefore, once the wood chip and wood fiber contain water, it is not necessary to spray water for about two days even in midsummer.

  In addition, wood chips and wood fibers generally change to dark brown when water is retained, that is, when water is contained, while when the amount of water retention of wood chips and wood fibers decreases, the color changes from dark brown to light brown. Therefore, by observing the plant cultivation container 10, it is possible to roughly grasp the amount of water retained.

The size of the wood chip and the wood fiber is not particularly limited, but the wood chip preferably has a vertical and horizontal length of 50 mm or less and a thickness of 5 mm or less, respectively. The wood fiber preferably has a maximum length of 80 mm or less, a vertical length that is at least three times the horizontal length, and a thickness of 5 mm or less. This is because such wood chips and wood fibers are likely to be mixed well together.
The water content of the wood chip and the wood fiber is preferably 150% or less.

Sand is contained in order to give moderate hardness and strength to the plant cultivation container 10. As for the particle size of the sand, it is preferable that the maximum particle size is 5 mm or less, and the passing amount percentage of 0.075 mm is 10% or less. When the sand has such a particle size, it can be mixed well with the wood chips and wood fibers, and the plant cultivation container 10 becomes a substantially uniform material. Moreover, it is preferable that the moisture content of sand is 10% or less.
Furthermore, it is preferable that the compounding ratio of sand is in the range of 10 to 40% in terms of volume ratio with respect to the total volume of wood chips and wood chips. If the volume ratio is lower than 10%, the strength of the bottom portion 11 and the side wall portion 12 is lowered, and as a result, the durability of the plant cultivation container 10 is lowered. On the other hand, if it is higher than 40%, the water retention of the bottom part 11 and the side wall part 12 is remarkably lowered.

  Nutrient body 16 has a substantially granular shape with a surface covered with a water-soluble film, and in addition to nitrogen, phosphorus, and potassium, which are called the three elements of fertilizer, calcium, magnesium, sulfur, manganese, Contains nutrients such as boron, iron, copper, zinc, molybdenum, and chlorine. The nutrients 16 are scattered inside the bottom part 11 and the side wall part 12. When water is supplied by watering, for example, the nutrients are eluted as shown by the arrow A4, and the nutrients are replenished to the plant 30. It is possible.

The moisture curable adhesive which is an adhesive in the first embodiment is for bonding wood chips, wood fibers, sand, and nutrients 16. The type of moisture curable adhesive is not particularly limited in the present invention. For example, a urethane-based moisture curable adhesive can be used. As the urethane-based moisture curable adhesive, there are known a one-component curable type and a two-component curable type. More specifically, a one-component curable moisture curable adhesive is generally cured at room temperature by the reaction of a modified urethane polymer having an isocyanate group (—NC (═O) —) with moisture in the air. The two-component curable moisture curable adhesive uses polyester polyol or polyether polyol as the main agent, uses polyisocyanate or the like as the curing agent, and mixes them to cure each other at room temperature. . Such a urethane-based moisture-curable adhesive has elasticity and toughness as well as durability and liquid resistance compared to an epoxy-based adhesive.
However, the adhesive is not limited to the moisture curable type, and may be other urethane type, emulsion type, one liquid curable type, two liquid curable type adhesives.

[Manufacturing method of container for plant cultivation]
Then, the manufacturing method of the container 10 for plant cultivation which concerns on 1st Embodiment is demonstrated with reference to FIG.
As shown in FIG. 2, the manufacturing method of the container 10 for plant cultivation which concerns on 1st Embodiment mixes the wood chip | tip 13 and the wood fiber 14, the sand 15, the nutrient 16, and the moisture hardening type adhesive agent 17. As shown in FIG. The first step of preparing the mixture 19 (hereinafter referred to as the wood chip mixture), the second step of placing the wood chip mixture 19 on the mold 53 coated with the release agent 54, and the placed wood chip mixture 19 Is cured within a range of 0 to 50 ° C., and a fourth step is performed to demold the cured wood chip mixture 19 from the mold.
Hereinafter, each step will be described in detail.

(First step)
First, as shown in FIG. 2 (a), the wood chip 13 and the wood fiber 14 are put into a mixing container 51, and this is stirred and sufficiently loosened by a mixer 52. 16 is added and kneaded for a predetermined time. After air kneading, a predetermined amount of moisture-curing adhesive 17 is added thereto, and further mixed with a mixer 52 to prepare a wood chip mixture 19.

Here, the wood chip 13 and the wood fiber 14 put into the mixing container 51 in the first step are in a wet state. This is because when the wood chip 13 and the wood fiber 14 are in a wet state, the water in the wood chip 13 and the wood fiber 14 reacts with the moisture-curing adhesive 17 so that the wood chip mixture 19 is cured early. .
In order to obtain a wet state, the wood chip 13 and the wood fiber 14 are preliminarily immersed in water or sprinkled with water. In addition, even wood chips 13 and wood fibers 14 having a high water content immediately after thinning and processing can be used as they are and do not need to be dried.

The addition amount of the moisture curable adhesive 17 is preferably within a range of 110 to 130 kg / m ^{3 with} respect to the total volume of the wood chip 13, the wood fiber 14, the sand 15, and the nutrient 16, most preferably 120 kg / m ³ .

(Second step)
Next, as shown in FIG. 2B, after assembling the mold 53 into a predetermined shape, a release agent 54 (release material) is applied to the inner surface of the mold 53 in the form of a thin film. As the formwork 53, it is preferable to use a water-resistant veneer board or the like that has been subjected to a surface treatment because it is easy to remove the mold. The type of the release agent 54 is not particularly limited in the present invention. For example, an easily available neutral detergent, silicon, or the like can be used.
Next, while placing the wood chip mixture 19 inside the mold 53 to which the release agent 54 is applied, the core 55 which is the inner mold is placed at a predetermined position. Further, when placing the wood chip mixture 19, the wood chip mixture 19 is appropriately compacted using a tamper or the like as necessary.
In this way, the release agent 54 is interposed between the placed woodp mixture 19 and the mold 53.

The core 55 is for forming the concave planting part 10a by removing the core 55 after the wood chip mixture 19 is cured as described later (see FIG. 2D). Therefore, the size and shape of the core 55 are appropriately changed according to the type of the plant 30 to be planted. Further, it is preferable to apply the release agent 54 to the surface of the core 55. When the release agent 54 is applied to the surface of the core 55 in this way, the core 55 is easily removed after curing.
Moreover, in 1st Embodiment, the core 55 formed from the polystyrene foam with small specific gravity is used. When the specific gravity of the core 55 is small as described above, the core 55 is temporarily disposed at a predetermined position of the placed wood chip mixture 19 and then the wood chip 55 is caused by its own weight during the curing of the wood chip mixture 19. It is possible to prevent the unscheduled planting portion 10a from being formed by sinking into the mixture 19. However, the present invention is not limited to this, and the core 55 may be fixed to the mold 53 via an appropriate arm.

(Third step)
Thereafter, as shown in FIG. 2C, the wood chip mixture 19 is placed on the mold 53, and the core 55 is placed at a predetermined position of the wood chip mixture 19, and the curing is performed at 0 to 50 ° C. It is cured at a predetermined curing time at temperature.
The reason for setting the curing temperature to 0 to 50 ° C. is that when the curing temperature is lower than 0 ° C., the curing reaction of the moisture curable adhesive 17 is reduced, so that the curing is difficult to proceed, while the curing temperature is higher than 50 ° C. This is because the curing time of the moisture curable adhesive 17 is shortened and may be cured during the production, or the moisture that should react with the moisture curable adhesive 17 may evaporate and disappear.
Further, the curing time varies depending on the amount of the wood chip mixture 19 and the curing temperature, etc., but as a result of examining the curing state of the wood chip mixture 19 under various conditions, it is preferable that the curing time is within a range of 4 to 8 hours. I understood.
Furthermore, by setting the curing temperature within the range of 10 to 25 ° C. (optimum range), the curing time of the moisture curable adhesive 17 can be set to a time that is not too short and not too long. It is possible to prevent the wood chip mixture 19 from being hardened rapidly, and the operation can be suitably performed.
Furthermore, a general adhesive is cured by evaporation of a solvent from the surface, etc., but as described above, the wet wood chip 13 and the wood fiber 14 are used, and the moisture curing adhesive 17 is used. Thus, since the moisture curable adhesive 17 is cured by reacting with moisture distributed throughout the wood chip mixture 19, the cured wood chip mixture 19, that is, the plant cultivation container 10, has a degree of curing. The strength distribution due to the difference is less likely to occur and the durability is increased.

(4th process)
After curing, as shown in FIG. 2 (d), the hardened wood chip mixture 19 is removed from the mold 53 and the core 55 is removed from the hardened wood chip mixture 19. The wood chip mixture 19 removed from the mold 53 is a plant cultivation container 10. Further, the wood chip mixture 19 and the mold 53 can be easily separated by the release agent 54 applied to the inner peripheral surface of the mold 53 at the time of demolding and interposed between the wood chip mixture and the mold 53. Yes, it can be removed without much effort.
Further, the surface of the wood chip mixture 19 that has been demolded may be smoothed by, for example, a trowel finish to improve the aesthetic appearance.

  Thus, according to the manufacturing method of the container 10 for plant cultivation which concerns on 1st Embodiment, the container 10 for plant cultivation can be manufactured easily.

  Furthermore, the plant cultivation container-plant complex 1 is prepared by putting the soil 20 into the planting part 10a of the plant cultivation container 10 produced above, planting a desired plant 30, and appropriately performing watering and curing. Easy to manufacture.

[Planting method]
Then, the planting method using the container for plant cultivation-plant complex 1 which concerns on 1st Embodiment is demonstrated with reference to FIG.
In addition, as shown in FIG. 3, the case where it plants along the curb 73 provided in the boundary of the roadway 71 and the sidewalk 72 is demonstrated here.

  First, between the curb stone 73 on the roadway 71 side and the sidewalk 72, an excavation groove 75 having a predetermined width is formed along the longitudinal direction of the road with an in-situ concrete 74, 74.

And the container for plant cultivation-plant complex 1 is continuously arrange | positioned inside the excavation groove | channel 75. FIG.
At this time, in general, in the plant rooted by the straw, it is necessary to backfill the soil while supporting the plant not to tilt when planting, but according to the container for plant cultivation-plant complex 1, Since the outer shape has a substantially rectangular parallelepiped shape as described above, it can be stably arranged, and there is no possibility that the plant 30 tilts. Therefore, it can plant suitably in the state in which the plant 30 was arranged without manpower.

  In addition, after planting, the plant cultivation container 10 rots with time, so that the root 30a of the grown and elongated plant 30 penetrates the plant cultivation container 10 as shown in FIG. The root 30a can be stretched around the ground G (soil or the like). Therefore, the plant 30 is planted suitably.

Second Embodiment
Next, the plant cultivation container according to the second embodiment will be described.
The container for plant cultivation according to the second embodiment is formed on the side wall portion 12 (see FIG. 1) of the container for plant cultivation 10 according to the first embodiment so that the ridge and the groove are opposed to each other and can be connected. It is characterized by that. According to the plant cultivation container in which the ridges and the groove are formed (hereinafter referred to as a grooved plant cultivation container), for example, a plurality of grooved plant cultivation containers can be easily connected and grooved. What connected the container for plant cultivation (Hereafter, this is called the container connection container for plant cultivation with a groove | channel) can be comprised easily.

  Therefore, when a plurality of types of plants 30 (see FIG. 1) are planted for each of a plurality of grooved plant cultivation containers, a desired plant is appropriately selected from the plurality of plants 30 to provide a grooved plant. By appropriately connecting the containers for cultivation, it is possible to easily construct a grooved plant cultivation container connected body in which a plurality of plants 30 are arranged.

<Third Embodiment>
Next, the plant cultivation container according to the third embodiment will be described.
The plant cultivation container according to the third embodiment is characterized in that the porosity increases as it goes upward in the height direction of the side wall portion. When the porosity increases in this way toward the upper side of the side wall, the air permeability is suitably increased on the upper side of the plant cultivation container, and excess water is easily discharged upward, so that the plant is less likely to rot.

  As mentioned above, although an example was described about suitable embodiment of this invention, this invention is not limited to the said embodiment, In the range which does not deviate from the meaning of this invention, it can change suitably.
